How high can i go with acrylic?

[Chin_Lee]

it depends how you build. If you have acrylic euro-bracing at the bottom and the top of the tank, I would go up to 36. Otherwise 30 is probably safe.

It depends on a few things, first off as stated length for sure as well as bracing but it's not about safety with acrylic. You could build a tank 4 feet tall with 1/2" and it would easily hold but it's the bow you have to worry about. Acrylic is softer than glass and will bow and bulge more which creates distortion. I wouldn't go any bigger than 4 feet in length and 2 feet in height using 1/2". Remember Acrylic is clear you can go as thick as you want without sacrificing clarity. Although it's stronger than glass an acrylic tank should use thicker material than a glass tank.

its would be 32" long and I would like to go 36"tall. Its being designed to fit into a specific location.

I would go thicker for sure, if it was my tank I still wouldn't go taller than 24" with that length and 1/2". Even a small amount of deflection will create distortion. Just make the viewable sides thicker, I would use 1" for that height.

I am curious, how much $$ wise do you figure you will save building it yourself? I have gotten a couple of quotes on acrylic (trimless/braceless) tanks, nothing more than 70gal and they seem to be around 700 (or a bit less, depending)..
